In the universe discovered the very first stars


An international team of astronomers has discovered the universe’s two most light of the first stars. Identified as SN2213 and SN1000 +2016, the stars are brightly shining rare class of supernovae, since the light from the explosion of 10-100 times brighter than the light produced by ordinary supernova explosions.

Various studies carried out in recent years, allowed the scientists to discover new information about the universe. Thus, the class was open and supersvetyaschihsya supernovae, which are brighter in the tens or hundreds of times normal supernovae. "Supernova" - a term denoting a star, in a flash of brilliance which increases by tens of stellar magnitudes.

Discover SN2213 and SN1000 +2016 helped 3.6-meter telescope of the CFHT, which is located in the Hawaiian Islands. CFHT telescope is the first device that allows a person to look far into the universe.

Processing images taken with the telescope has been performed in Canada, the University of Toronto using a technique designed to observe gravitational redshift. Stars with a redshift of 2.05 and 3.90 exploded, presumably, more than 10 billion years ago, when the universe was much younger than his current age.

"It’s pretty hard to find supersvetyaschiesya supernovae SN2213 and SN1000 +2016, because there are a lot of stars and galaxies and supernovae may be required to eliminate. The main question was to separate the very distant galaxies first. They have been located so far, that there would not be visible ordinary supernovae. So we found belonged to the class supersvetyaschihsya star supernovae. These cosmic objects are interesting in that store a lot of information about the conditions and types of stars that formed after just one billion years after the Big Bang ", said Ray Carlberg, an astrophysicist at the University of Toronto.
